DETAILED DESCRIPTION
[0028] The specific embodiments of the utility model are further described below according to the drawings:
[0029] An underground surveying traverse point protection device, comprising a traverse point and a protection device.
[0030] As Figures 1-2 shown, the traverse point comprises cylinder 1 and end 2, and end 2 is rotatably connected to the top of cylinder 1, and the top of end 2 is uniformly provided with a plurality of wire slots 3 for embedding and placing the traverse wire.
[0031] The protection device comprises a connecting rod driving mechanism and block 11, and end 2 is drivingly connected to block 11 through the connecting rod driving mechanism, through hole 12 is arranged on the side wall of cylinder 1, block 11 is arranged in through hole 12, and block 11 extends out of the outside of cylinder 1 after penetrating through through hole 12.
[0032] End 2 is used for sliding block 11 in and out along through hole 12 by the connecting rod driving mechanism when rotating.
[0033] In this embodiment, the connecting rod driving mechanism is arranged inside the cylinder column 1, and the connecting rod driving mechanism comprises a support column 4, a rotating disc 5, a driven shaft 15, a support shaft 8 and a screw rod 10.
[0034] As shown in Figures 4-7 The end head 2 is connected with the rotating disc 5 through the support column 4, four driven shafts 15 are rotatably connected on the cylinder column 1, and the four driven shafts 15 are distributed around the rotating disc 5. The rotating disc 5 is in transmission connection with the plurality of driven shafts 15. Each driven shaft 15 is in transmission connection with a support shaft 8. One end of the support shaft 8 is rotatably connected with the cylinder column 1. The support shaft 8 is internally threadedly connected with the screw rod 10. The abutting block 11 is connected at the end of the screw rod 10. The abutting block 11 is square. The through hole in the outer circumferential surface of the bottom of the cylinder column 1 is a square through hole. The abutting block 11 penetrates through the square through hole. The abutting block 11 provides a limiting condition for the movement of the screw rod 10 by being embedded in the square through hole.
[0035] In this embodiment, a main gear 16 is connected on the outer edge of the rotating disc 5. A secondary gear 17 for meshing with the main gear 16 is connected on the top end of the driven shaft 15. The driven shaft 15 is vertically arranged and rotatably connected with the cylinder column 1 at the bottom end. The worm structure 9 is arranged on the driven shaft 15. The worm wheel structure 6 matched with the worm structure 9 is connected on the outer side of the support shaft 8.
[0036] In this embodiment, a plurality of supports 14 are fixedly connected on the inner wall of the cylinder column 1. The shaft sleeve 7 for supporting the rotation of the support shaft 8 is connected on the support 14. The support shaft 8 is rotatably connected with the shaft sleeve 7.
[0037] In this embodiment, the plurality of support shafts 8 are horizontally arranged, including two upper support shafts 8 and two lower support shafts 8. The axes of the upper support shafts 8 and the lower support shafts 8 are in a non-planar vertical state.
[0038] In this embodiment, the outer wall of the abutting block 11 is in an arc structure consistent with the cylinder column 1, and is provided with a rough tooth surface structure 13.
[0039] In order to protect the wire point during the installation of the wire point in the shaft, the wire point needs to be divided into two parts, i.e. the cylinder column 1 and the end head 2. The end head 2 rotatably arranged on the cylinder column 1 not only serves as the top end of the wire point containing a plurality of wire grooves 3, but also serves as a part for rotating the rotating disc 5 in the cylinder column 1 by being held by hand.
[0040] In the shaft, a counterbore slightly larger than the cylinder column 1 is drilled by a drill bit. The wire point is placed in the hole. The abutting block 11 is extended and tightly pressed against the hole wall, so as to stably install the wire point in the shaft.
[0041] On this basis, the block 11 with the tooth surface structure 13 slightly protruding from the cylinder 1 and closely attached to the hole wall can be selected to repeatedly rotate the end 2 of the handheld guide wire point relative to the cylinder 1, and the tooth surface portion 13 is used to rub the hole wall to form a small recess in the hole, and the block 11 is embedded into the small recess to further enhance the effect of stable placement of the guide wire point; and the guide wire point is protected to avoid tilting and affecting the downhole guide wire measurement.
[0042] In the embodiment, the support shaft 8 is rotated by the cooperation of the worm gear structure 6 and the worm structure 9 under the rotation of the support column 4 and the rotating disc 5. Since the block 11 at the end of the screw rod 10 in the support shaft 8 is square and is also embedded into the square through hole in the cylinder 1, the block 11 provides a limiting condition for the extension and retraction movement of the screw rod 10 in the support shaft 8, so that the block 11 can advance towards the hole wall under the rotation of the handheld end 2. Through reasonable size design, the block 11 will not completely protrude from the square through hole, lose the limiting effect and have the opportunity to return to the guide wire point.
[0043] In the specific implementation, the guide wire point with the protection device is used for measurement operation in the well. Before installation, a drill bit is used to drill a hole position slightly larger than the guide wire point part at the position of the guide wire point in the well. In the installation stage, the guide wire point is placed into the hole position, and the guide wire point is placed in the hole in a vertical and upright state. At this time, the cylinder 1 and the end 2 part are held by two hands respectively, the end 2 is rotated, the block 11 at the bottom of the hole position will move out, move towards the hole wall, and finally tightly attach to the hole wall, so that the guide wire point is vertically erected and is difficult to tilt. On the basis of the above operation, the block 11 can be selected to be closely attached to the hole position, and the cylinder 1 part is slightly rotated within a certain range by force, the rough tooth surface structure 13 of the block 11 is used to horizontally excavate some space on the hole wall bottom plate, and the block 11 is further protruded into the excavated space, so that the stable protection effect of the guide wire point is better.
[0044] The utility model and its implementation mode are described above, and the description is not restrictive. The embodiment shown in the drawings is only one of the embodiments of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
